President Trump joined onstage by ex-Maricopa County Sheriff Joe Arpaio during a campaign rally in Iowa in January 2016.

Trump-boosting Arizona Senate candidate Joe Arpaio, who was pardoned by the President last year after being convicted of contempt of court, refused Thursday to rebuke an anti-Semitic outlet that he has given several interviews to.

Arpaio, the controversial ex-sheriff of Maricopa County, has given at least five interviews to the conspiracy theory-touting American Free Press website since 2014. The website, which features plenty of Confederate-era imagery, touts controversial headlines such as "Jewish Fingerprints All Over 9-11."

Arpaio, who's made headlines for his hardline anti-immigration stance, was interviewed for a story by the anti-Semitic publication published Tuesday. The story, which describes Arpaio in flattering terms, focuses on his recently announced run for the U.S. Senate seat currently held by Sen. Jeff Flake.

Asked about the Tuesday story, Arpaio told the Arizona Republic that he bets "it was a good interview."

"He's written some good stories, especially on my situation," Arpaio said of the story's author, "roving editor" Mark Anderson. "I think he wrote one a little while back that was very honest. I can't say that for other publications."

"What am I supposed to do? Investigate every media outlet to see what stories they write?" he added.

"I'm not going to criticize the news media like you," Arpaio told a reporter about the anti-Semitic publication.

Arpaio was found guilty last fall of unfairly targeting Hispanic people while serving as sheriff. A judge blasted Arpaio for stopping and rounding up Hispanic residents solely because he suspected that they were in the country illegally.

The judge's ruling could have resulted in six months of home confinement for Arpaio, but Trump unexpectedly stepped in and pardoned him last August. In a pardoning statement, Trump praised the ex-sheriff for supposedly "protecting the public from the scourges of crime and illegal immigration."

Earlier this month, Arpaio announced his Senate campaign, declaring in a statement that he's running "for one unwavering reason: to support the agenda and policies of President Donald Trump."

American Free Press, the controversial publication Arpaio spoke to, was founded by Willis Carto, an Indiana man whom the Anti-Defamation League describes as a "white supremacist."

Carto, who died in 2015, was also the founder of the extreme-right Liberty Lobby as well as the Holocaust-denying Institute for Historical Review.
